What is a typical effect on traffic when a rate limit is exceeded on an F5 BIG-IP?

Traffic is load balanced to another pool

Traffic is throttled or delayed

An administrator configures an iRule on a virtual server to rate-limit requests from each client IP to 10 requests per second. The iRule uses a sliding window counter. A client sends 15 requests in one second. What is the expected behavior for the 5 excess requests?

They are rejected or dropped according to the iRule's action (e.g., HTTP::respond or drop).

They are allowed but the client's IP is temporarily blacklisted.

They are all processed normally because the limit is per minute, not per second.

They are queued and processed once the next second begins.

An administrator configures an iRule to rate-limit requests per client IP to 10 requests per second. The iRule uses a fixed window counter. A client sends 15 requests in the first second, then 5 requests in the next second. What is the expected behavior?

The first 10 requests in the first second are allowed, and the remaining 5 are rejected. In the second second, all 5 requests are allowed.

All 20 requests are allowed because the total over two seconds is within the limit.

The first 15 requests are allowed, and the 5 in the next second are rejected.

All 20 requests are queued and processed at a rate of 10 per second.
